Authorities are looking into possible connections between the disappearance of Santa Barbara City College student Brianna Denison from a Reno home and other crimes committed in that area. They are still looking for a white man in his mid-30s believed to have information about her disappearance. Also, blood found on Denison’s pillow may indicate that she was restrained or suffocated with the pillow, police said. Anyone with information should call (775) 745-3521.
